Filed: 1961-10-11
Abstract: 958,600. Delivering sheets. S. D. WARREN CO. Oct. 11, 1961 [Dec. 28, 1960], No. 36518/61. Heading B6H. [Also in Division B8] Apparatus for handling sheets of paper or the like comprises a feeding device and an endless belt conveyer having plates secured to the belt along their leading edges so that they extend tangentially from the belt as it passes around a roller adjacent the device, thus leaving a gap for the introduction of a sheet between the trailing edge of each plate and the belt. Sheets 10 cut from a web are fed between rollers 10, 14. The roller 14 is carried on brackets 16 which are pivoted at 18 and also carry on a transverse member 22 a series of blocks 24 each securing a shaft 28 supporting a compressed air chamber 46 supplied with air through the shaft 28. The shafts and blocks are adjustably secured by set screws 30, 26. A plurality of chambers 46 are thus spaced across the width of the sheets. The chamber comprises a lower surface curved in sheet feed direction and provided with a plurality of parallel slit openings 48 through which air is directed to the right along the surface to form a film of air between the surface and a sheet, thereby reducing the pressure and causing the sheet to move along the surface. The sheet is then deflected downwardly by a surface 49. A conveyer comprises four belts 50 which each has secured thereto by cementing or otherwise a series of rigid nylon plates 62 which constitute grippers which open as the belt passes over the toothed rollers 54, 56. Each sheet is gripped by a gripper on each belt and pulled along the lower run thereof until it is either dropped at the further end by the opening grippers, or is removed from the grippers by stop members 72 positioned between the belts.

Title: Improvements in or relating to manufacture of highly resilient corrugated tubes
IPC: B21D15/10
Filed: 1946-12-11
Abstract: 627,730. Making tubes ; corrugating. METALLSCHLAUCHFABRIK AKT.-GES. Dec. 11, 1946, No. 36633. Convention date, Dec. 27, 1945. [Classes 83 (ii) and 83 (iv)] In a method of making resilient corrugated tubes, preliminary corrugations are formed in a thin walled metal tube by the application of internal pressure by means of a solid resilient material such as rubber, the uncorrugated portion of the tube adjacent the pressure applying means being free to move axially during the application of the pressure, the corrugations being then axially upset while maintaining the inner pressure at least during the first part of the upsetting operation. A rubber ring 6 is compressed beneath a punch 2 to form the initial bulge which is then upset axially by the descent of a guide tube 10. Then the pressure on the ring 6 is released and the corrugation completed by the further lowering of the tube 10. The die 7, which in a modification may be displaceable instead of the tube 10, is then opened, the work-piece 1 lowered until the corrugation fits in a groove 8 in the die, and the process is repeated. The press may be horizontal or vertical. Specification 541,406 is referred to.

Title: Numerical data processing systems
IPC: G06F13/18
Filed: 1970-07-29
Abstract: 1,269,301. Priority access to digital data memory. COMPAGNIE INTERNATIONALE POUR L'INFORMATIQUE. 29 July, 1970 [31 July, 1969], No. 36748/70. Headings G4A and G4C. A digital data memory can be accessed by a number of processor units, each unit being capable of generating a request signal and/or a high priority request signal, the requests being evaluated in order of priority by an interpreter I. The processors can be digital computers UC0, UC1, a data exchange E having one peripheral unit (e.g. magnetic disc or drum), data multiplex exchanges UE4 to UE6 having a number of peripheral units, or two multiplex exchanges UE1, UE2 sharing a party line. Each processor has a respective request line DA0 to DA7 and a high priority request line HP0 to HP7. Operation (Fig. 2).-When a request signal arrives on an input DA it passes through an AND gate 5N0 to 5N7 (which AND gate is only enabled if a bi-stable BPN is set), and an OR gate 60 to 67, to set a respective bi-stable MR0 to MR7. A signal is also sent via OR gate 70 to AND gate 71 (which is only enabled by signal ML if the memory is available for access) and thence via OR gate 73 to a delay line DL. The first output a of line DL resets bi-stable BPN thus temporarily blocking further requests. At the same time bi-stable 75 is set which enables the bi-stables MR0 to MR7 to give an output if they have received a pulse. When the signal reaches b on line DL, bi-stable 75 is reset and the signal from the appropriate store MR0 to MR7 passes to a control line CA0 to CA7 and thence to an inverter I0 which keeps AND gates 5N0 to 5N7 blocked. The lines have a priority which decreases from CA0 to CA7 and a signal on any line passes via an inverter I 1  to I 7  to block any signal on a lower priority line. When the signal reaches c on line DL, a pulse passes to AND gate 74. If there is a high priority request this gate 74 is enabled and the memory signals non- accessibility. Simultaneously bi-stable BHP is set which enables high priority request gates 5P0 to 5P7 and these requests are processed when a signal at point d enables AND gate 72. The waveforms at various time periods are also described (Figs. 3A to 3C, not shown). When a high priority request is made it also sends an ordinary request though this is optional in which case there is no connection between inputs DA0-DA7 and gates 5P0 to 5P7. The multiplex exchanges are also described in some detail (Fig. 4, not shown).

Title: Improvement in the production of polyvinyl alcohol yarns
IPC: D01F6/14
Filed: 1960-11-01
Abstract: Polyvinyl alcohol yarns, free from spinning solvent, are drawn at 180 DEG -230 DEG C. in the vapour of a boiling organic liquid boiling within this temperature range at atmospheric pressure, and which, in this temperature range, is a non-solvent for, and chemically inert to, the polyvinyl alcohol.  The term "yarns" is so defined as to include tows.  The term "polyvinyl alcohol" includes long-chain synthetic polymers composed of at least 50% by weight of vinyl alcohol units.  The vapour may be saturated or superheated, and may be that of a hydrocarbon, e.g. decahydronaphthalene, or an alcohol, e.g. benzyl alcohol.  In Examples (1), a 145 denier, 20 filament, 1,3 turns per inch polyvinyl alcohol yarn is drawn 6x in decahydronaphthalene vapour at 198 DEG C., at a yarn speed of 490 feet/minute with a residence time in the vapour of 0,28 seconds, (2), an identical yarn is drawn 6,5x in benzyl alcohol vapour at 205 DEG C., at a yarn speed of 525 feet/minute.  The process of the invention reduces the time otherwise necessary to bring yarns into thermal equilibrium, and thus enables drawing to be effected in apparatus of reduced dimensions.
